LUBRICATOR.

Specification of Letters Patent.

Patented Mar. 30, 1915.

Application led February 4, 1914. Serial No. 816,417.

To all whom it may concern.'

Be it known that I, Homan HANSEN, a citizen of the United States, residing at the borough of Manhattan, in the city, county, and State of New York, have invented an Improvement in Lubricators, of which the following is a specification.

My resent invention relates to a lubricator, in the use of which gra hite is maintained in suspension, in the ubricant employed with the apparatus.

In lubricatin various types of machinery, as is well un erstood, it is advantageous to mix a certain amount of graphite with the lubricant. I am aware that heretofore lubricators have been constructed by employing various mechanical means for carrying out the objects of my present invention. For example, I am aware that mechanically actuated blades or paddles have been employed in lubricators in attempts to maintain raphite in suspension in the lu bricant. Ign all of these devices, however, so far as I am aware, the space in which the graphite is maintained in suspension and properly mixed with the lubricant is retrict-V ed to the immediate area in which the mechanical devices are operated.

The object of mg present invention is the provision of a lu ricator in which I. employ means for pneumatically maintaining the graphite in suspension in the lubricant, so that the mixture of the graphite and lubricant is ractically uniform throughout its entire vo ume.

In car g out my invention, I preferably empidyl a casing adapted to contain the lubricant, means for regularly supplying air to the interior of the casing, so that the same passes through the mixture of aphite and lubricant, devices for actuating the aforesaid means, as well as devices for positively suplllyingthe mixed aphite and lubricant to t e parts to be lu ricated,

.as-will be hereinafter more particularly de- Ascribed. i

Ii'rthe drawing, Figure lis a central lonpiston 18, secured to which is a proved lubricator. Fi 2 is an elevation in partial cross section o the same, taken in a position at 90 to that shown in Fig. 1.

Referring to the drawing, I prefer to emplo in carrying out my invention, a receptac e, indicated at 10. This, as will be understood, may be made of any suitable material, and is opened at one end and provided with a cover 11. In the base or lower end of the receptacle, a chamber 12 is provided. At the inner end of this chamber, a valve casing 13 is secured. Within the valve casing is a check valve 14 normally bearing against a valve seat 15 and maintained in position thereon by means of a spring 1G acting between the upper end of the valve and the inner surface of a cap 17, suitably secured on the valve casin 13. In the walls of this valve casing, in suitably spaced positions, are arranged a number of downwardly inclined discharge ports, indicated at 51. Within the chamber 12, I employ a iston rod 19, which passes throu h a suitab e packing gland 20. Adjacent t e lower end of the casing, the same is provided with an air inlet port 21, making communication between the interior of the chamber 12 and the atmosphere. Also in the lower end or base of the receptacle 10 I provide supply chambers, indicated at 22 and 23, respectively, preferably extendin longitudinally of the receptacle. In the c amber 22 is a plunger 24, and in the chamber 23 a similar plunger 25. The plunger 24 passes through a suitable packing gland 26, and similarly the plun er 24 passes through the packing glan 27 At their outer ends, the plungers 24 and 25 are suitably connected to a head .28. The head 28 is also connected to the piston rod 19, b means of a in 43, or other` wise, so that t e iston ro and plungers mzy be actuated simultaneously.

n the supply chamber 22 I employ a ball check valve 29, adapted to seat against the valve seat provided for therein, and in the supply chamber 22 there is also an internal gitudinal cross section illustrating my im-y4 flange or ring 30, which determines the extent of the movement of the valve 29 in one direction. Similarly, in the supply chamber 23, I employ a ball check valve 31, also adapted to bear against the valve seat provided therefor within the supply chamber 23, in which there is also an internal flange or ring 32 which determines the extent of the travel of the ball check valve 3l in one direction.

Suitabl placed in the receptacle 10, there is a disc large outlet 33, controlled by a needle valve 34 or other similar device. lhis outlet connection permits of the supply of the mixed lubricant and graphite from the outlet 33, through suitable px es 35 and 36, to the suppl lchambers 22 an 23 respectively, from w ich, as will be understood, suitable pipe connections may be made to the parts to be lubricated.

Connected in a suitable position to the receptacle 10 is a bracket lug 37, secured to which is an arm 38. A lever 39 is pivotally connected at the free end of the arm 38, as indicated at 40, and the free end of the lever 39 is connected within a yoke 41 at the end of the piston rod 19 by means of a pin 42 or otherwise. The receptacle 10 is also provided with a bracket lug 44, to which is connected a bracket 45 for supporting the lubricator by being suitably secured to any part of the mechanism to be lubricated.

As shown in the drawing, the receptacle 10 may be provided with a gage glass 46, and the pipes 47 and 48, from the respective supply chambers, may be passed through the interior of the receptcle and throug-h the cover 11 thereof. As also indicated in Fig.'

1, the cover 11 is provided with a 4port or vent opening 49, and ma also be provided with an opening for fillm r the receptacle, this opening being normallly closed by a plug, indicated at 50.

In the operation, of the hereinbefore described lubricating apparatus, the iston rod 19, together with its iston 18, an the plungers 24 and 25, are simultaneously actuated by the lever 39, which is suitably connected to moving parts of the machine or devices to be lubricated. The travel 'of the iston is suflicient, when' at the end of its o wnward stroke, to uncover the port 21, thereby admitting atmospheric air to the piston chamber 12. On the upward strike of the piston, the air soadmitted forces open the check valve 14, moving the same against the sprin 16, permitting this air to escape into and t rough'themxxture of graphite and lubricant'nnd to p assfrom the interior of the receptacle'through the vent'49.

FAS the distribution of the air is uniform and regular, the' graphite will bemaintained lin"suspe'nsion in the lubricant so "thatthe' mixturethereof will'bel uniform. 'As'will also be apparent, the mixture of graphite and lubricant is fed through the outlet 33, controlled by the needle valve 34, and conveyed by the pipes 35 and 36 to the supply chambers 22 and 23, from which, each time the plungers 24 and 25 more upwardly, a predetermined quantity of the lubricant is forced by thc check valves 29 and 31, into the pipes 4T and 48, respectively, and thence to the parts to be lubricated.

It will furthermore be understood that whileI have shown and described two supply chambers and pipes leading therefrom, that any number'of these supply chambers and supply pipes may be employed without departing from the nature and spirit of my invention.
